Product Introduction:
Our double roller extrusion granulator is an advanced dry compaction system designed specifically for producing high-quality compound fertilizer granules without liquid binders or thermal drying. Utilizing German-engineered hydraulic technology, this industrial-grade granulator delivers superior particle density and production efficiency for modern fertilizer plants.

Working Principle:

1. Pre-Mixed Feeding - Uniformly blended raw materials are fed into the granulator chamber

2. High-Pressure Compaction - Twin rollers apply 50-100MPa mechanical pressure to physically bond particles

3. Flake Formation - Materials emerge as continuous dense sheets with controlled thickness

4. Precision Crumbling - Specialized flake breakers create uniform semi-finished granules

5. Particle Refinement - Multi-stage screening and polishing achieve final spherical granules

6. Recycling System - Oversized particles are automatically crushed and reintroduced

Material Compatibility:
• NPK formulations (15-15-15, 17-17-17, etc.)
• Diammonium/Monoammonium Phosphate (DAP/MAP)
• Potassium fertilizers (SOP/MOP)
• Specialty fertilizer blends
• Mineral powders

Mainly including compound fertilizer production equipment, organic fertilizer production line equipment, double-roll press granulat
